The key is whether you want real information or if something that is an approximation to varying degrees of accuracy is good enough for your fishing.

All of the "home" methods are rife with errors when it comes to the Actual Breaking Strength and you need a truly professional method to be accurate, as well as to be safe.

If you are very careful you can come up with "seat of the pants" numbers that may be good enough for your purposes. If you are using it for comparing lines then you really need something more consistent so as to not mislead.

What the major difference is what I want to know... Okay, Paulusjustfishing.com has done a great job, but how do I know the line I have bought is not fake. Braid is not so cheap. A friend recently bought an Avet SX with my consultation that had been machine spooled with 40lb green Tuf-line XP. According to the seller, he ordered it from a very well known online shop, one that I also trust. When we tested it through our crudest method of pulling as gradually as we could with a weighing scale, it snapped at 22-23lb! Even if I keep a margin of error of 10lb, Tuf-line 40lb should still break at well above 30lb!

In a real fishing situation, the fish will jerk and pull the line as hard it could... of course you can fight a 40 pounder with 40lb line, but you can also fight it on 20lb because of your drag setting.

I am not arguing or trying to prove anything but I want to get rid of this confusion in my mind. Okay I may not be able to eliminate the slightest jerks at home, but a 40lb TEST line should be able to suspend a 40lb weight without snapping. Or am I wrong?

I guess you are talking about testing the actual breaking strength of the line while I just wanna be sure a 40lb test line will be able to hold 40lb of force... then only can I set my reel drag at 10-12lb with confidence!

Thanks!

paulos tested some line(aust;)

igfa tested the same line(usa)
they were different by a big margin

pretest mono is MAYBE the best mono
braid on average will be 25% overstated b/s
I do the same as keta,thinness dia; for given b/s,8ply +
its a lottery
cheers

For such simple purposes you can use a spring scale used for weighing fish (shimano). Anchor the line, pull on it with the scale and it will record where it breaks.

The first variable is what knot or how you anchored the line. As any knot weakens the line it will be breaking at the knot and the breaking strength will reflect your choice of knots and tying skill. If it is not breaking where you tied it and/or it is breaking far below listed strength then the line is defective or not as sold.

Typically however, a "40lb" braid will test on a pro machine from 50-60+lbs BUT, when knotted can be well under 40 depending on tying skill and knot choice...which is why we talk about the 'best knot' all the time and people like me emphasize tying skill

.

The "pro" methods have machines that anchor the line over drums etc to completely eliminate knots.

Many people try to test braided line. Without high tec, and high cost equipment there testing is flawed. Ask Mark at Charkbait he will tell you the equipment he has is not up to the task. Paulus has the stuff. Mark would give his eye teeth to have the equipment, and so would I.

I have not tested braid since I don't use it but somewhere on the site is a picture of me lifting a 40 lb dumbbell with 40 lb momoi diamond line with a three turn SDJ knot and a Newell 533 5.5 reel. Best way to test that I know of.

I can't claim to be a knot expert but my knots have so far not failed on me. I would be happy to see my braid break at knots. So far it's breaking in the middle and that is alarming!

Those are more like rod tests, and rods being tested to their limits. The angle is even above 90 degrees. I wouldn't dare load my rods at that angle!

Spectra/PE tends to break around 8 to 12 " from a connection. The connection usually does not break unless it is very poor. Paulus has a lot of info on his site about home testing. One thing that might help is to test a known, quality product or two. Keep the results and use it as a bench mark. And the result will give you a % compared to the bench mark. Also keep in mind that diameter is a big factor. A few millimeters have a big effect on spool capacity. I quit trying to find out the actual breaking strength. There are to many variables. Strength %, diameter, workability, and cost are the factors I use in deciding if I use a line.
Hope this helps.

Paulus may have perfected the braid testing system, it means nothing out there in the open. I believe, IGFA should come up with a braid testing with a bimini loop or some other standard at one end because that is what will be used during actual fishing. If I have 40lb braid on my reel that Paulus may have tested at 50lb, but it is breaking at 25lb in the home tests, then chances are, it will break around 25lb out at sea because I will tie a leader to it, and the fish is gonna shake its head in no polite manner!
